options:

• has no effects on the heart

Explanation:

First Question (Long - term brain condition due to vitamin B1 deficiency)

Wernicke - Korsakoff syndrome is a long - term brain disorder that is caused by a deficiency of vitamin B1 (thiamine). Parkinson's disease is related to dopamine - related neuronal issues, multiple sclerosis is an autoimmune disorder affecting the nervous system, and Alzheimer's disease is associated with amyloid plaques and tau tangles. So the correct option is the one with Wernicke - Korsakoff syndrome.

Regular excessive alcohol consumption is known to raise blood pressure. Raised blood pressure increases the risk of heart disease and stroke. It does not lower blood pressure, strengthen the heart muscle in a positive way (excessive alcohol is bad for the heart), and it does have effects on the heart. So the correct option is the one stating it raises blood pressure and increases the risk of heart disease and stroke.

Answer:

B. Wernicke - Korsakoff syndrome
